Uncomfortable:
Passage of catheter is not very pleasant. Radiologist can use Lidocaineanesthetic gel. Voiding during and first void after study may sting a little. Essentially not painful. Request addition of antibiotic like gentamicin to the xray contrast fluid used to reduce risk of introducimg a uti.

My take ...:
VCUG is a special X-Ray exam to visual if one has bladder-to-ureter / kidney reflux (backflow) or urethral stricture while voiding. For details of its current or evolving indication, techniques, alternatives, etc. over the past 2-3 decades, ask the radiologist timely.

Cystografin contrast:
Is the "dye" used, it is introduced through a catheter and is not medication. I personally have gentamicin 80mg added to the cystografin before instillation into bladder to reduce the mild risk of causing a UTI to virtually nil.

A retrograde urethrogram is when a tiny catheter is put into the opening of the urethra (penis in males) and pictures are taken as the dye is injected backwards. A voiding study is the opposite, contrast is put into the bladder with a catheter and pictures are taken as the patient pees the contrast out.

Here are some ...:
For postvoid incontinence, I assumed you have so-called postvoid dribbling after you ripped in the penis into underwaer, which is indeed very annoying. You may try correctly milking the entirely urethra after each voiding by wiping the urethra x 3-4 times from the area behind scrotum toward the end of penis until "dryness" before zipping in the penis.

It doesn't look like from your history you have a known urethral stricture and there are other causes for nocturia (e.g. diabetes, bladder problems) so I'd recommend assessment by a doctor licensed in your area to sort through the possibilities and order tests if needed.

Here are some ...:
Some sandy sedimentation may appear, especially after being exposed air for 15-30 minutes through oxidation while urine is more alkaline with pH of >6.5, usually reflecting what you might have consumed. Besides changing its cloudiness, its odor will also alter to be more odorous. But, these changes is normal and harmless as long as complete urinalysis from properly collected urine specimen is okay

Premature:
Ejaculation is sometimes called ill-timed ejaculation. It is a subjective evaluation. You may orgasm too quickly and not satisfy your partner. If you have concerns you can see your doc or a licensed sextherapist. It is not an illness. Please ask your urologist or your doc about the stricture question. Peace and good health.

Unusual:
No reason why U should be incontinent of urine after a circumcision. Surgery does not affect urethra unless circumcision performed grossly incorrectly. Suggest you consult an experienced urologist & not surgeon who performed your operation.
